There is a department in the underworld called the Department of Human Sojourn.
Not everyone will obediently reincarnate after death. Previously, a ghost who was unwilling to reincarnate made a fuss and overturned the pot of soup that Meng Po was cooking, causing those ghosts to reincarnate without drinking the soup.
The King of Hell received dozens of letters of complaint, and the Ministry of Human Detention was created.
Souls with obsessions and no karmic obstacles during their lifetime can apply to have their wishes fulfilled by employees of the Human Residence Department.
And Meng Ranxing is an old employee in the love brain department. She is responsible for changing the outcome of the love brain. As long as she does ten more orders, she can be reincarnated.
Purpose: Love brain is not necessary
